Given away at a young age Olivia wanted to find out who her true parents were. She always knew that apart of her was missing that she wasn't like the others, she was special. When Princess Diana passed away suddenly everyone mourned her death, for Olivia it felt like something else was missing that apart of her died. Years later thanks to a surprise visit to Kensington Palace she found out that she was apart of the royal family and a lot like her mother. I don't even think the Palace was prepared for a Princess Undone.
